function. However, this may result in
minor personal injury if someone is
behind the vehicle when the switch is
activated, or damage to the lift gate.
NOTE:
.To avoid damaging the lift gate system,
do not manually force the lift gate to
open or close when the lift gate is
moving. When manually operating the
lift gate from the full close or full open
position, do not use excessive force.
Using excessive force may damage the
system.
. Do not install accessories such as bike
racks onto the lift gate. The additional
weight of these accessories may cause
the lift gate to operate slowly or to not
open completely. This is a normal
operation and does not indicate a
malfunction. The lift gate will operate
normally when the accessory is re-
moved.
. If the lift gate is opened when the
vehicle is parked on a steep slope, the
lift gate may not open to the expected
position. This is a normal operation
and does not indicate a malfunction. .
If the automatic lift gate is operated
continuously for approximately 180
seconds, the system automatically
turns off to prevent overheating. The
lift gate cannot be opened using the
switches. The system resets and opera-
tion returns to normal after approxi-
mately 180 seconds. This is a normal
operation and does not indicate a
malfunction.
. The lift gate may automatically reverse
direction if the lift gate is operating
and passengers enter/exit the vehicle.
This is a normal operation and does
not indicate a malfunction.
. The lift gate must be operated manually
if the battery is disconnected or
discharged.
. If the lift gate is not activated due to a
low voltage (less than approximately
11V), operate the lift gate with the
engine running.
Manual mode
If power operation is not available, the lift
gate can be operated manually. Power
operation may not be available if multiple
obstacles have been detected in a single
power cycle or if the battery voltage is low. When the power lift gate main switch is in
the OFF position, the lift gate can be
opened manually by pushing the lift gate
opener switch. If the power lift gate opener
switch is pushed during power open or
close, the power operation will be canceled
and the lift gate can be operated manually.
AUTO CLOSURE
If the lift gate is pulled down to a partly
open position, the lift gate will pull itself to
the closed position.
Do not apply excessive force when the
auto closure is operating. Excessive force
applied may cause the mechanism to
malfunction.
CAUTION
.
The lift gate will automatically close
from a partly open position. To avoid
pinching, keep hands and fingers away
from lift gate opening.
. Do not let children operate the lift gate.

cause a fire.
CAUTION
.Do not use leaded gasoline. Deposits
from leaded gasoline seriously reduce
the three-way catalyst’s ability to help
reduce exhaust pollutants.
. Keep your engine tuned up. Malfunctions
in the ignition, fuel injection, or elec-
trical systems can cause overrich fuel
flow into the three-way catalyst, causing
it to overheat. Do not keep driving if the
engine misfires, or if noticeable loss of
performance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly by an INFINITI retai-
ler.
. Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
. Do not race the engine while warming it
up.
. Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance, and it is the driver’
s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem may not be able to detect or signal low
tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons,
including the installation of replacement or
alternate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.

5-10Starting and driving
by strong side winds. Slower speeds
ensure better vehicle control.
. Do not drive beyond the performance
capability of the tires, even with AWD
engaged.
. For AWD equipped vehicles, do not
attempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
. Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer (such
as the dynamometers used by some
states for emissions testing), or similar
equipment even if the other two wheels
are raised off the ground. Make sure you
inform test facility personnel that your
vehicle is equipped with AWD before it is
placed on a dynamometer. Using the
wrong test equipment may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury. (AWD
models)
. When a wheel is off the ground due to an unlevel surface, do not spin the wheel
excessively.
. Accelerating quickly, sharp steering
maneuvers or sudden braking may cause
loss of control.
. If at all possible, avoid sharp turning
maneuvers, particularly at high speeds.
Your vehicle has a higher center of
gravity than a conventional passenger
car. The vehicle is not designed for
cornering at the same speeds as con-
ventional passenger cars. Failure to
operate this vehicle correctly could
result in loss of control and/or a rollover
accident.
. Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Install tire chains on the rear
wheels when driving on slippery roads
and drive carefully.
. Be sure to check the brakes immediately
after driving in mud or water. See “Brake
system” (P.5-80) for wet brakes.
. Avoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or sideways,
you could be injured. .
Whenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent maintenance
may be required. See the maintenance
information in the “INFINITI Service and
Maintenance Guide”.
. Spinning the rear wheels on slippery
surfaces may cause the AWD warning
light to flash and the AWD system to
automatically switch from the AWD
mode to the 2WD mode. This could
reduce traction. Be especially careful
when towing a trailer. (AWD models)

5-14Starting and driving
.Make sure the area around the vehicle
is clear.
. Check fluid levels such as engine oil,
coolant, brake fluid and window
washer fluid as frequently as possible,
or at least whenever you refuel.
. Check that all windows and lights are
clean.
. Visually inspect tires for their appear-
ance and condition. Also check tires for
proper inflation.
. Lock all doors.
. Position seat and adjust head re-
straints.
. Adjust inside and outside mirrors.
. Fasten seat belts and ask all passen-
gers to do likewise.
. Check the operation of warning lights
when the ignition switch is pushed to
the ON position. (See “Warning/indica-
tor lights and audible reminders” (P.2-
13).) 1. Apply the parking brake.
2. Move the shift lever to the P (Park) or N
(Neutral) position. (P is recommended.)
The starter is designed not to operate
unless the shift lever is in either of the
above positions.
3. Push the ignition switch to the ON position. Depress the brake pedal and
push the ignition switch to start the
engine.
To start the engine immediately, push
and release the ignition switch while
depressing the brake pedal with the
ignition switch in any position.
.If the engine is very hard to start inextremely cold weather or when
restarting, depress the accelerator
pedal a little (approximately 1/3 to
the floor) and while holding, crank
the engine. Release the accelerator
pedal when the engine starts.
.If the engine is very hard to startbecause it is flooded, depress the
accelerator pedal all the way to the
floor and hold it. Push the ignition
switch to the ON position to start
cranking the engine. After 5 or 6
seconds, stop cranking by pushing
the ignition switch to OFF. After cranking the engine, release the
accelerator pedal. Crank the engine
with your foot off the accelerator
pedal
by depressing the brake pedal
and pushing the push-button igni-
tion switch to start the engine. If the
engine starts, but fails to run, repeat
the above procedure.
CAUTION
Do not operate the starter for more than 15
seconds at a time. If the engine does not
start, push the ignition switch to OFF and
wait 10 seconds before cranking again,
otherwise the starter could be damaged.
4. Warm-up
Allow the engine to idle for at least 30
seconds after starting. Do not race the
engine while warming it up. Drive at
moderate speed for a short distance
first, especially in cold weather. In cold
weather, keep the engine running for a
minimum of 2 - 3 minutes before
shutting it off. Starting and stopping
the engine over a short period of time
may make the vehicle more difficult to
start.
